地震反应谱计算方法，可以对于地震进行预测监控，方便及时进行相关措施减少人员伤亡和财产损失。(The calculation method of seismic response spectrum, earthquake prediction can be convenient for monitoring, timely measures to reduce casualties and property losses.)

偏态t分布分布函数，密度函数，对数似然函数，逆分布函数，随机模拟等等程序，对应学习偏态t分布的初学者特别适用(This zip file contains 5 functions: the pdf, cdf, log-likelihood, inverse cdf and a function to generate random draws the skewed t distribution.)

这是通信系统仿真的第六章的例题的仿真程序代码！挺好的，希望对大家有用！(This is a communication system simulation examples of Chapter VI of the simulation program code! Very good, and I hope useful for everyone!)

这个程序是用matlab编写的，主要使用于等离子显示器动态轮廓消除仿真！(This program is written using matlab, mainly used in plasma display dynamic contour eliminate simulation!)

利用simulink 仿真分析变压器谐波(Using simulink Simulation to Analyze Transformer Harmonic)

一个简单的优化案例。求解下面的带有等式约束和简单的边框约束(box constraints)的优化问题： minx,y(x?1)2+(y?2)2s.t.0≤x≤3,1≤y≤4,2x+3y=5(A simple optimization case. To solve the following with equality constraints and simple edge constraint optimization problem (box constraints): Minx, y (x - 1) 2+ (Y - 2) 2s.t.0 = x = 3,1 = y = 4,2x+3y=5)

说明：  用matlab计算泰勒展开式taylorseries、函数求导differentiate、求极限limitx、求解非线性规划nolinearsolve&ff5(Using MATLAB to calculate Taylor series, differential function differentiation, limit x, nonlinear programming nolinearsolve & FF5)

这是线性议程组的直接解法，有十种不同的解法（这与迭代解法是不同的）……(This is the direct linear solution of the agenda of groups, there are dozens of different method (which is different from the iterative solution) ... ...)

说明：  matlab仿真，ofdm的收端和发端程序源代码，欢迎下载(matlab simulation, ofdm client and the originator of the received source code are welcome to download)
